Abstract
Vascular smooth muscle cells respond with an increase in intracellular Ca2+ within seconds after exposure to oxidized low density lipoprotein (oxLDL). This has been suggested to represent a signaling response that may have implications for gene expression. If so, oxLDL may induce increases in nuclear Ca2+ in smooth muscle cells in response to oxLDL. Aortic smooth muscle cells were exposed to 100 microg/ml oxLDL. Large, rapid increases in [Ca2+]i were observed using fluo-3 as an indicator dye to detect intracellular Ca2+ on the stage of a confocal microscope. This was also confirmed using ratiometric imaging of indo signals. These elevations appeared to be localized to the nuclear region of the cell. DNA staining of the cells confirmed its localization to the nuclear/perinuclear region of the cell. Our data demonstrate that oxLDL induces a nuclear localized elevation in Ca2+i that may have important implications for nuclear function.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
